OPRAH isn’t shy about her love for Barack Obama, but she’s trying to keep secret the party she’s throwing in honor of his inauguration. An insider told us: “Oprah is planning a lavish bash at TenPenh,” a swanky Asian-fusion restaurant in DC. “She’s being extremely secretive about it,” said our source. “But there will definitely be a ton of A-listers there.” She will also be hosting her show from Washington next week. A rep for Oprah insisted, “She is not having a party.”
